Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration and treatment technology, and in particular to a modular, assembled, high-efficiency wastewater treatment equipment. Background Technology

[0002] In the current wastewater treatment field, with the diversification of industrial production, the increasing complexity of urban domestic sewage composition, and the differentiated wastewater treatment needs of various scenarios (such as small communities, industrial parks, and temporary construction sites), traditional wastewater treatment equipment is gradually revealing significant limitations. Traditional wastewater treatment equipment often adopts an integrated, fixed structural design, with its filtration units and main equipment being inseparably integrated. Once the equipment is manufactured, its filtration levels, filtration precision, and treatment capacity are fixed, making it impossible to flexibly adjust according to the actual wastewater quality (such as suspended solids content, organic matter concentration, and specific pollutant types) and treatment requirements. For example, when treating low-concentration domestic sewage, some high-precision filtration units in traditional equipment may be in an "over-filtration" state, not only wasting energy and consumables but also reducing overall treatment efficiency due to unnecessary filtration steps. Conversely, when treating high-concentration industrial wastewater, traditional equipment often requires additional auxiliary treatment devices due to insufficient filtration unit functionality, leading to increased equipment footprint, complex installation and commissioning, and difficulty in quickly responding to emergency wastewater treatment needs. Furthermore, if the filter unit of traditional equipment is damaged or aged, the entire equipment often needs to be shut down for disassembly and repair. This not only results in high maintenance costs but also interrupts the wastewater treatment process, affecting the continuity and stability of the treatment system. These problems mean that traditional wastewater treatment equipment cannot meet the diverse and flexible wastewater treatment needs in terms of adaptability, economy, and efficiency. Therefore, a modular, assembled, high-efficiency wastewater treatment equipment is proposed to solve the aforementioned problems. Utility Model Content

[0003] This invention addresses the problem that existing devices cannot meet the diverse and flexible wastewater treatment needs of today by providing a modular, assembled, high-efficiency wastewater treatment device. By setting multiple independently detachable filter units, one or more corresponding filter units can be precisely selected and assembled without modifying the main body of the device, effectively solving the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows:

[0005] A modular, assembled, high-efficiency wastewater treatment device includes a bottom cylinder. The upper end of the bottom cylinder is provided with multiple detachable filter units. Each filter unit includes an assembled filter barrel. Both the assembled filter barrel and the top end of the bottom cylinder have snap-fit ​​connectors. The lower end of each assembled filter barrel has snap-fit ​​grooves. Each assembled filter barrel contains a filter plate. A rotatable connecting cylinder is located at the center of each filter plate. A scraper that mates with the filter plate is located on the outer surface of each connecting cylinder. A detachable collection box is installed on the inner wall of each filter plate. A connecting shaft is located at the lower end of each connecting cylinder. A rotatable drive cylinder is located at the center of the bottom cylinder. Spline grooves that mate with the connecting shaft are located on the inner walls of both the drive cylinder and the connecting cylinder.

[0006] A funnel is fixedly connected to the lower end of the bottom cylinder, a cross seat is fixedly connected to the inner wall of the bottom cylinder, a first motor is fixedly connected to the lower end of the cross seat, and a drive cylinder is installed at the output end of the first motor.

[0007] The filter plates are all fixedly connected to the inner wall of the assembled filter barrel, the connecting cylinders are all rotatably connected to the inner wall of the filter plates, and the scrapers are all fixedly connected to the outer surface of the corresponding connecting cylinders.

[0008] The inner wall of each filter plate is provided with an opening groove, and the collection box is slidably connected to the inner wall of the corresponding opening groove.

[0009] The inner wall of each collection box has multiple through holes.

[0010] The outer surface of the assembled filter barrel is fixed with a sealing cover, and both the sealing cover and the inner wall of the assembled filter barrel are provided with mounting holes that match the collection box.

[0011] The inner wall of each sealing cover is provided with a sealing door that can move up and down. The inner wall of each sealing cover is also provided with an elastic structure that cooperates with the collection box. When the sealing door moves upward to open the mounting hole, the collection box can pop outward under the action of the elastic structure.

[0012] All the sealing doors are slidably connected to the inner wall of the sealing cover, and each sealing door has a handle fixedly attached to its upper end.

[0013] Each of the elastic structures includes two support ear plates fixed to the sealing cover, and springs are fixed to each support ear plate. Extended ear plates that cooperate with the springs are provided on both ends of the collection box.

[0014] Each of the supporting ear plates is also fixedly connected to a telescopic rod, and each telescopic rod has a retaining pad fixedly connected to its telescopic end, with springs sleeved on the corresponding telescopic rods.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] During use, the corresponding filter unit is selected according to the filtration requirements. Multiple filter units can be selected for multi-stage filtration of wastewater. When the first motor is started and the connecting cylinder rotates, it drives the scraper to move circumferentially. During this movement, the scraper cleans impurities from the upper part of the filter plate, pushing them into the collection box. The collection box is detachably installed on the inner wall of the filter plate. When the collection box is full, it can be removed and replaced. This modular, assembled, high-efficiency wastewater treatment equipment breaks the limitations of traditional fixed structures by setting multiple independently detachable filter units. Users can precisely select and install one or more filter units according to the specific wastewater quality characteristics of the application scenario, such as filtration of domestic sewage, industrial wastewater, and medical wastewater, or according to the treatment objectives such as suspended solids removal, organic matter degradation, and adsorption of specific pollutants, without modifying the main body of the equipment. For example, in small-scale community wastewater treatment scenarios… It can be equipped with only primary filtration and biodegradation units; in high-concentration wastewater treatment scenarios in industrial parks, advanced oxidation filtration units and activated carbon adsorption units can be added to achieve efficient adaptation to different scenarios; since the equipment can flexibly select filtration units according to actual filtration needs, it avoids the problems of "over-filtration" or "under-filtration" of traditional equipment; when treating low-difficulty wastewater, reducing unnecessary investment in filtration units can reduce equipment operating energy consumption and consumables, such as the consumption rate of filter membranes and activated carbon; when treating high-difficulty wastewater, by adding targeted functional filtration units, it can avoid substandard treatment and the need for secondary treatment due to missing filtration links, which can significantly improve the efficiency and pass rate of single filtration; at the same time, the modular design allows each filtration unit to operate and maintain independently. When a unit malfunctions, only that unit needs to be disassembled for repair or replacement, without the need for shutdown for maintenance, further ensuring the continuous operating efficiency of the overall equipment and reducing the risk of wastewater treatment stagnation due to equipment failure.

Detailed Implementation

[0025] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-7 As shown, this utility model provides a modular assembled high-efficiency sewage treatment equipment, including a bottom cylinder 1. The upper end of the bottom cylinder 1 is provided with multiple detachable filter units. Each filter unit includes an assembled filter barrel 7. Both the assembled filter barrel 7 and the bottom cylinder 1 have snap-fit ​​connectors 8 at their upper ends. The lower end of the assembled filter barrel 7 has snap-fit ​​grooves 9. The assembled filter barrel 7 is provided with filter plates 10 inside. Each filter plate 10 has a rotatable connecting cylinder 22 at its center. Each connecting cylinder 22 has a scraper 11 on its outer surface that cooperates with the filter plate 10. Each filter plate 10 has a detachable collection box 12 installed on its inner wall. Each connecting cylinder 22 has a connecting shaft 13 at its lower end. The bottom cylinder 1 has a rotatable drive cylinder 6 at its center. Both the drive cylinder 6 and the inner wall of the connecting cylinder 22 have spline grooves that cooperate with the connecting shaft 13.

[0027] like Figures 1-4As shown, multiple support legs 2 are fixed to the outer surface of the bottom cylinder 1. The support legs 2 support the entire device. By installing the snap-fit ​​groove 9 of the assembled filter barrel 7 onto the corresponding snap-fit ​​connector 8, each filter unit can be assembled and used. The snap-fit ​​connector 8 and the snap-fit ​​groove 9 are interference fits, allowing each filter unit to be disassembled and selected according to filtration requirements. The inner wall of the filter plate 10 has multiple filter holes, and the size of the filter holes in each filter unit is different. The corresponding filter unit can be selected according to filtration requirements. When multiple filter units are selected, multi-stage filtration of sewage can be performed. The rotatable connecting cylinder 22 drives the scraper 1 when it rotates. 1. Circular movement: When the scraper 11 moves in a circular motion, it can scrape the impurities on the upper end of the filter plate 10, thereby pushing the impurities into the collection box 12. The collection box 12 is detachably and washably installed on the inner wall of the filter plate 10. When the collection box 12 is full of impurities, it can be removed and replaced. 2. Connecting shaft 13 can be inserted into the inner wall of the corresponding spline groove. When the connecting shaft 13 is inserted into the spline groove, when the drive cylinder 6 rotates, it can drive the connecting shaft 13 and the connecting cylinder 22 to rotate synchronously, that is, the corresponding scraper 11 moves in a circular motion, so that the scrapers 11 in each filter unit start working. This modular assembled high-efficiency sewage treatment equipment breaks through the limitations of multiple independently detachable filter units by setting up multiple detachable filter units. This design overcomes the limitations of traditional fixed structures. Users can precisely select and install one or more corresponding filter units based on the specific wastewater characteristics of their application scenario, such as filtration of domestic sewage, industrial wastewater, and medical wastewater, or based on treatment objectives such as suspended solids removal, organic matter degradation, and adsorption of specific pollutants, without requiring modifications to the main equipment. For example, in small-scale community wastewater treatment scenarios, only primary filtration and biodegradation units can be installed; in high-concentration wastewater treatment scenarios in industrial parks, advanced oxidation filtration units and activated carbon adsorption units can be added to achieve efficient adaptation to different scenarios. Because the equipment allows for flexible selection of filter units according to actual filtration needs, it avoids the limitations of traditional equipment. The system addresses the issues of "over-filtration" or "under-filtration." When treating low-difficulty wastewater, reducing unnecessary filtration unit investment lowers energy consumption and material consumption rates, such as the depletion of filter membranes and activated carbon. When treating high-difficulty wastewater, adding targeted functional filtration units avoids substandard treatment and the need for secondary treatment due to missing filtration stages, significantly improving the efficiency and pass rate of single filtration. Furthermore, the modular design allows each filtration unit to operate and be maintained independently. If a unit malfunctions, only that unit needs to be disassembled for repair or replacement, eliminating the need for system shutdown and ensuring continuous operation of the entire equipment, thus reducing the risk of wastewater treatment stagnation due to equipment failure.

[0028] A funnel 3 is fixedly connected to the lower end of the bottom cylinder 1, a cross seat 4 is fixedly connected to the inner wall of the bottom cylinder 1, a first motor 5 is fixedly connected to the lower end of the cross seat 4, and a drive cylinder 6 is installed at the output end of the first motor 5.

[0029] like Figures 2-3 As shown, the bottom of the funnel 3 is equipped with a valve, which can release filtered water when the valve is opened; the cross seat 4 supports and fixes the first motor 5 and the drive cylinder 6. The drive cylinder 6 is rotatably connected to the inner wall of the cross seat 4. When the first motor 5 is started, the drive cylinder 6 can be rotated. The motor and the valve are existing technologies and will not be described in detail.

[0030] The filter plates 10 are all fixedly connected to the inner wall of the assembled filter barrel 7, the connecting cylinders 22 are all rotatably connected to the inner wall of the filter plates 10, and the scrapers 11 are all fixedly connected to the outer surface of the corresponding connecting cylinders 22.

[0031] like Figure 4 As shown, the filter plate 10 can limit and support the connecting cylinder 22, so that the connecting cylinder 22 can only rotate. When the connecting cylinder 22 rotates with the connecting shaft 13 and the drive cylinder 6, it can drive the scraper 11 to move in a circle.

[0032] The filter plate 10 has opening slots on its inner wall, and the collection box 12 is slidably connected to the inner wall of the corresponding opening slot.

[0033] like Figures 4-5 As shown, the collection box 12 can slide left and right on the inner wall of the opening groove, so that the collection box 12 can be disassembled and replaced.

[0034] The inner wall of the collection box 12 is provided with multiple through holes.

[0035] like Figure 5 As shown, the through holes facilitate the filtering of impurities in the collection box 12, and prevent the impurities in the collection box 12 from containing water when it is removed.

[0036] The outer surface of the assembled filter barrel 7 is fixed with a sealing cover 14, and the sealing cover 14 and the inner wall of the assembled filter barrel 7 are provided with mounting holes that cooperate with the collection box 12.

[0037] like Figures 4-5 As shown, the collection box 12 is easily removed and disassembled through the mounting hole, and the sealing cover 14 is used to seal the mounting hole to prevent liquid from leaking out of the mounting hole.

[0038] The inner wall of each sealing cover 14 is provided with a sealing door 15 that can move up and down. The inner wall of each sealing cover 14 is also provided with an elastic structure that cooperates with the collection box 12. When the sealing door 15 moves upward to open the mounting hole, the collection box 12 can pop outward under the action of the elastic structure.

[0039] like Figures 4-5As shown, the sealing door 15 is used to open or close the mounting hole of the sealing cover 14. When the sealing door 15 moves upward, the mounting hole is opened. At this time, the collection box 12 can be ejected outward under the elastic force of the elastic structure, so as to facilitate the removal of the collection box 12. When the sealing door 15 moves downward to close the mounting hole, the collection box 12 is in the innermost stable position and can collect impurities.

[0040] All the sealing doors 15 are slidably connected to the inner wall of the sealing cover 14, and each sealing door 15 has a handle 16 fixedly connected to its upper end.

[0041] like Figure 6 As shown, the sealing door 15 is slidably connected to the inner wall of the sealing cover 14, and the sealing door 15 can be easily moved up and down by the drive handle 16.

[0042] Each of the elastic structures includes two support ear plates 18 fixedly connected to the sealing cover 14, and springs 19 are fixedly connected to each support ear plate 18. Extended ear plates 17 that cooperate with springs 19 are provided on both ends of the collection box 12.

[0043] like Figure 6 As shown, the supporting ear plate 18 supports and limits the spring 19. When the collection box 12 moves inward, the extended ear plate 17 can squeeze the spring 19. When the sealing door 15 moves downward to the bottom, the mounting hole of the sealing cover 14 is closed and can block the collection box 12 to prevent it from popping out. When the sealing door 15 moves upward to fully open the mounting hole, the extended ear plate 17 and the collection box 12 can pop outward under the elastic force of the spring 19, which makes it easy to remove and replace the collection box 12.

[0044] Each of the supporting ear plates 18 is also fixedly connected to a telescopic rod 20, and each telescopic end of the telescopic rod 20 is fixedly connected to a retaining pad 21. Springs 19 are all sleeved on the corresponding telescopic rod 20.

[0045] like Figure 7 As shown, the telescopic rod 20 can limit the stop pad 21, so that the stop pad 21 can only move inward or outward. The spring 19 always has an outward driving force on the stop pad 21, so that the stop pad 21 is at the outermost end under normal conditions. When the extension ear plate 17 moves inward, it can contact the stop pad 21, thereby squeezing the spring 19.

[0046] In use, this utility model allows for the selection of appropriate filter units based on filtration requirements. When multiple filter units are selected, multi-stage filtration of wastewater is possible. When the first motor 5 is started, causing the connecting cylinder 22 to rotate, the scraper 11 moves circumferentially, scraping impurities from the upper part of the filter plate 10 and pushing them into the collection box 12. The collection box 12 is detachably and washably installed on the inner wall of the filter plate 10. When the collection box 12 is full of impurities, it can be removed and replaced. This modular, assembled, high-efficiency wastewater treatment equipment breaks the limitations of traditional fixed structures by setting multiple independently detachable filter units. Users can precisely select and assemble one or more corresponding filter units based on the specific wastewater characteristics of the application scenario, such as filtration of domestic sewage, industrial wastewater, and medical wastewater, or based on treatment objectives such as suspended solids removal, organic matter degradation, and adsorption of specific pollutants, without modifying the main body of the equipment. For example, in In small-scale community wastewater treatment scenarios, only primary filtration and biodegradation units need to be installed. In high-concentration wastewater treatment scenarios in industrial parks, advanced oxidation filtration units and activated carbon adsorption units can be added to achieve efficient adaptation to different scenarios. Since the equipment can flexibly select filtration units according to actual filtration needs, it avoids the problems of "over-filtration" or "under-filtration" of traditional equipment. When treating low-difficulty wastewater, reducing unnecessary investment in filtration units can reduce the energy consumption and consumables of the equipment, such as the consumption rate of filter membranes and activated carbon. When treating high-difficulty wastewater, by adding targeted functional filtration units, it can avoid substandard treatment and the need for secondary treatment due to missing filtration links, which can significantly improve the efficiency and pass rate of single filtration. At the same time, the modular design allows each filtration unit to operate and be maintained independently. When a unit has a problem, only that unit needs to be disassembled for repair or replacement, without the need for shutdown for maintenance, which further ensures the continuous operating efficiency of the overall equipment and reduces the risk of wastewater treatment stagnation due to equipment failure.
